推荐答案

不要那样做. PrintForm可以-ish-，但是您确实想正确地完成这项工作.使用 PrintDocument [ ^ ]-它提供了更好的服务控制，以及看起来更好地作为打印对象.该链接包含一个示例. Don''t do it that way. PrintForm is ok -ish- but you really want to do the job properly. Use a PrintDocument[^] instead - it provides a lot better control, and well as looking better as a printed object. The link includes an example.
